HSII PLOW – INTRODUCTION HSII OPERATOR’S MANUAL

2015 1.3

Directional Control Valve (Plow) A separate section of the control valve is required for each hydraulic function of the plow.

• Front swing • Rear swing • Main lift • Shank attitude • Adjustable shank (if included in plow assembly) • Hydraulic capstan laydown (if included in plow assembly)

The control valve is normally mounted on the right hand side of the operator, thereby permitting a rear view of the plow’s shank and chute and a forward view of the tractors direction. The hydraulic hoses for connection between the tractor, control valve and hydraulic manifold that is mounted on the main mast of the plow are to be supplied by the installing dealer. Hydraulic hose sizes from the directional control valve to the plow’s manifold should be of the same diameter as the respective fittings at the manifold. Refer to Hydraulic hose specification for hose diameter sizing and specifications. If a flow divider is required in the hydraulic system (i.e. for capstan and/or power rewind), the pressure line from the tractor’s pump is connected to the pressure-in (pump port) of the control valve.

NOTE On some tractors, a separate pump may be installed. In this case, the power beyond and tank are connected together and the return line runs

directly back to the tank through a filter.

The return line should be connected near the bottom side of the tank and deflected away from the suction line. An alternative is to go into the top of the tank with a standpipe, down to the bottom of the tank and deflect it away from the suction line. Refer to the hydraulic schematic for location and attachment of the directional control valve.

Half Inch Directional Control Valve (Capstan and/or Power Rewind) If a capstan and/or power rewind is part of the plow assembly, than a directional control valve is required. A single section valve is required to operate either the capstan or the power rewind. If both the capstan and power rewind is part of the same plow assembly, than a dual section control valve is required. This valve functions as an on/off in addition to controlling the direction (forward/reverse) of the capstan sheave and/or the power rewind wheel. This control valve should be mounted in a convenient location to the right hand side of the operator. Dealer supplied hydraulic lines are required to connect to and from this valve. The hydraulic hose should be ½” diameter 100R2 specification or equivalent (rated for 3000 PSI working pressure). Refer to the hydraulic schematic for the location and attachment of the ½” directional control valve.

HSII PLOW – INTRODUCTION HSII OPERATOR’S MANUAL

2015 1.4

Flow Divider (Capstan and/or Power Rewind) If a capstan and/or power rewind is part of the plow assembly, than a flow divider is required. This valve diverts 10 gallons per minute of controlled flow to the directional valve. It should be mounted between the tractor pump and the main directional control valve; the size of flow divider required is determined by the GPM of the tractor pump and should have been specified at time of order. Dealer supplied hydraulic lines are required to connect to and from this valve. Refer to Hydraulic hose specification for hose diameter sizing and specifications. Refer to the hydraulic schematic for the location and attachment of the control valve.

Hydraulic Adjustable Shank For plow assemblies equipped with this option, an additional section is required in the directional control valve. This section must be connected to the appropriate lines on the hydraulic manifold that is mounted on the main mast of the plow assembly. This additional section controls the shank height from the minimum to the maximum depth permissible depending on plow model and shank dimension. The shank is held in position with a double lock valve when the directional valve section is in neutral. Dealer supplied hydraulic lines are required to connect from the directional control valve section to the plow manifold.

Hydraulic Capstan Laydown For plow assemblies equipped with this option, an additional section is required in the directional control valve. This section must be connected to the appropriate lines on the hydraulic manifold that is mounted on the main mast of the plow assembly. Dealer supplied hydraulic lines are required to connect from the directional control valve section to the plow manifold.

FLOW CAPACITIES OF HOSE ASSEMBLIES AT SUGGESTED FLOW VELOCITIES The chart on the next page is designed and provided as an aid in the determination of the correct hose size. Example: At 13 Gallons per minute, what is the proper hose size within the suggested velocity range for pressure lines? Solution: Locate 13 gallons per minute in the left hand column and 10 feet per second in the right hand column (the centre of the suggested velocity range for pressure lines). Lay a straight edge across these two points. The inside diameter required to give the desired velocity is the actual inside diameter shown in the centre column nearest the straight edge. For suction hoses, follow the same procedure except use suggested velocity range for intake.

** Suggestions are for oils having a maximum viscosity of 315 S S U at +100° F. (+38° C.) and operating at temperatures between +65° F. and + 155° F. (+54° C. to +69° C.). Under certain conditions velocities in pressure lines can be increased up to 25 feet per second.

Based on formula:

AREA (SQ. IN.) = G.P.M. x 0.3208

Velocity (FT/SEC)

PRE-OPERATION CHECK LIST 1. Prior to any movement of the plow functions, lubricate all points as per lubrication guide on the following pages. 2. Ensure that all hydraulic lines, valves, etc. that may have been installed within the tractor cab are properly guarded to protect the

operator in case of any hydraulic ruptures. 3. Check the hydraulic oil system to ensure that it is filled to the tractor manufacturer's specs. 4. Prior to operation of hydraulics, ensure that no air is trapped in the circuit. 5. Start tractor and engage each function control of the plow and related accessories to ensure that the proper connections have been

made and that there are no interference fits. 6. Check all hydraulic connections for leaks. 7. Check all fasteners to ensure that they are properly torqued. 8. To protect hydraulic circuit and pump, line pressure must not exceed 3200 PSI.

To set pressure at 3200 PSI: a) Install pressure gauge in pressure line between tractor pump and directional control valve. b) Activate main lift cylinder to raise plow to maximum position. Hold control lever open to build up line pressure. c) Adjust relief setting in manifold inlet section of directional control valve to obtain 3200 PSI reading in the pressure gauge.

9. Ensure that the hydraulic lines to the hydraulic capstan laydown are bled of air before attempting to operate.

LUBRICATION POINTS Reference lubrication drawing on the following page.

Location Description Number of Points 1 Front swing 3 per cylinder 2 Rear swing 3 per cylinder 3 Lift cylinder 3 per cylinder 4 Main mast 2 5 Upper link 4 6 Lower link 4 7 Rear link 3 8 Hydraulically adjustable shank spacer bar 1 9 Hydraulic capstan laydown 5

Lubricate daily with good quality multi-purpose grease.

OPERATION

Main Directional Control Valve

Main Lift This section controls the lift cylinder(s) and raises/lowers the plow assembly.

Front Swing This section controls the two front swing cylinders connected to the backplate and main mast of the plow assembly. These cylinders activate the offsetting of the plow, right and left of centre. This section contains a float detent. To place from swing cylinder into float, pull control lever hard towards operator. If directional control valve has been incorrectly mounted, in upside down position, than cylinders should be in float during most plow conditions other than plowing on steep side slopes or when plowing in maximum offset position. Operator preference and experience will determine ultimate use of the float detent.

Rear Swing This section controls the parallel direction of the shank and chute. The shank and chute should be parallel to the tractor during plowing mode.

HSII PLOW – INTRODUCTION HSII OPERATOR’S MANUAL

2015 1.13

Attitude This section controls the angle of attitude of the shank. By angling the point of the shank towards the tractor, the shank will want to ride out of the ground. If the shank point is angle back away from the tractor, the shank will want to plow deeper into the ground. Once the desired plow depth has been achieved, the shank attitude should only be used to maintain desired depth.

Adjustable Shank Lift This section raises and lowers the shank. When the directional valve section is in neutral, the shank is held in position with a double lock valve.

Capstan Laydown Assembly

NOTE Ensure that both locking bolts are always in place prior to using the capstan.

The capstan when upright and in operating mode is held in position by two nuts and bolts. Prior to laying down the capstan for transport, remove these two nuts and bolts. The control section of the directional control valve is used to raise or lower the capstan.

Capstan and/or Power Rewind. The half-inch directional valve (single or dual) controls the direction of the capstan sheave and/or power rewind wheel. The hydraulic motor for the capstan and power rewind wheel required 10 GPM, from the power source through the speed control, to operate the motor and develop a maximum of 96 wheel revolutions at full engine RPM. The speed control will regulate the sheave/wheel RPM from 0 (off) to maximum. Torque pressure of the sheave/wheel is 450 pounds at a maximum relief setting of 2000 PSI.
